I have been trying to create an interchange properly in AIM and I'm finding it may not understnad the difference between a ramp and intersection. I have a freeway with 4 lanes in each direction, a median with guard rail, and shoulders (large cross section). I'm trying to add a ramp but the only way I can get the ramp to connect to the freeway is by moving the endpoint to the center of the freeway. The result is an awkward looking transition and all my lane striping disappears much like an intersection. Also, when I taper from 4 to 3 lanes, the transition is abrupt. I'm hoping there is a setting or a work around for these 2 issues. Any ideas or guidance is much appreciated.
At the moment that is the level of granularity we have for lane changes and merge/exit scenarios. Both are high on our priority list. If you wanted to have a deeper discussion around your requirements please feel free to contact me.
If I were to create my interchange in AIM, could I bring that into Civil 3D, make the necessary design tweaks in Civil 3D, and then bring it back into AIM?
